$PECIFICATION forming part of Letters Patent No. 382,292, dated May 8, 1888.

Application filed November 29, 1867. Serial No. 256,392. (No model.)

To all whom, it may concern.-

Be it known that I, LOUIS GAMPIOHE, a resident of St. Oroix, Switzerland, have invented certainnew and useful Improvements in Music- Boxes, of which the following is a specification.

My invention relates to sundry improvements in music-boxes, more particularly to that class of music-boxes wherein the pin barrel or cylinder is shifted to change the tune by means of a cam-plate-which bears against the end of said cylinder.

The invention consists in the novel arrangements and combinations of parts, that will be more fully hereinafter set forth.

Reference is to be had to the accompanying drawings,-forming part of this specification, in which Figurel is a plan view, partly broken, of a music-box embodying my invention. Fig. 2 is a detail sectional plan View showing one end of the pinbarrel and the actuating-cam, the section being taken on the line 0 c, Fig. 7. Fig. 3 is an end view of the pin-barrel. Fig. 4. is a side view of the pin-barrel, partly in section, the section being taken on the line k k, Fig. 3. Fig. 5 is a detail plan view of the tune-recorder, its top plate being removed. Fig. 6 is a vertical cross-section on the line 0'0, Fig. 1. Fig. 7 is a longitudinal section on the line k is, Fig. 6. Fig. 8 is a face view of the under side of the plate which covers the tune recorder, and Fig. 9 is a face view of the camplate for shifting the pin-barrel.

' A in the drawings represents the bed plate or frame of a musicbox.

B is the casing which incloses the main driving-spring, of suitable construction.

D is the pin barrel or cylinder, rigidly mounted upon a shaft, a, which passes centrally through said cylinder and extends beyond its ends. (See Fig. 4.) At one end the shaft a carries a handle or stop, I). At its other end said shaft carries a disk, d, preferably of convex form on its outer face, as shown. The disk' at carries an arm or pin, 6, adapted to enter a recess on the edge of a corresponding disk, f, on the drivingshaft g. The disk f is carried by a sleeve, f adapted to slide on and to be rotated by the driving-shaft g. This shaft g is suitably j ournaled in the base-plate A, and is rotated in suitable manner by the main spring. A spring, h, surrounding the shaft g, serves to press the disk f toward and against the disk (1, thereby crowding the pin-barrel endwise against a suitable stop. The speedregulating gear may be of approved form.

In the drawings the pin-barrel D is shown removable, and is supported in slotted bearings i, the shaft a resting in the slots of said bearings, as in Fig. 6. When the pin-barrel 50 is placed in position the arm 0 on the disk d passes in the slot in the disk f, whereby the pin-barrel is locked to the driving-shaft g. A guide, if, carried by oneof the bearing-pieces 2', serves to crowd the pin-barrel toward the disk f as it is being placed in the box to prevent its striking the shifting-cam. The convex meeting faces of the disks d and f permit of the ready insertion of the pin-barrel. WVhen the pin-barrel is in position, the spring h, by means of the disks d and f, presses the shaft or, and thereby the pin-barrel, against its stop. This stop in the drawings is represented as a camplate, E, (see Figs. 2 and 9,) by means of which the barrel is shifted to change the air. This 7 cam -plate or air-changer is described in an application for Letters Patent filed by me May 5, 1887, Serial No. 237,184. In the drawings it is shown mounted on a short shaft, j, journaled on a block, Z, that is carried by the baseplate A. 1

The cam-plate E has a number of points, m, each at different distances from the pivot of the cam, thereby making a number of camfaces, a. The points or are adapted to enter a 8 recess, 0, on the end of the pin-barrel D. Each time the pin-barrel makes a revolution a point,

m, enters the recess 0. The continued revolution of the barrel D turns the plate E slightly, bringing the next cam-face, n, against the end 0' of the barrel. As each cam-facen is presented to the pin-barrel,said barrel will be shifted longitudinally a slight distance, thereby presenting different teeth to the comb F. It is often desirable to play a tune out of consecutive order, or to pass, say, from the first to any other tune without playing the intermediate ones. This may be accomplished with the above construction by simply turning the shaft j by hand, which in turn rotates the cam-plate E, its camfaces a thereby shifting the pin-barrel the desired distance. When thelast tune in order has I recesses, p, one foreach canrface a.

been played, the next turn of the pin-barrel will present the inner earn-face, a, to the pinbarrel, when the spring It will press the barrel so as to com mcncc the first tune again.

It the cam-plate E were permitted freedom of rotation at all times, the same tune could only be played once before passing to the next. \Vith the following construction I am enabled to repeat a tune as often'as desired, and also 10 to prevent the cam-plate E rotating with the pin-barrel until the proper time, when it will be released and then locked again.

The cam-plate E is provided on one face (preferably its upper) with a series of holes or A spring, q, secured near one end to the block I, carries a pin, 1', adapted to enter one of the reccssesp at a time. The normal pressure of the spring (1 holds the pin '1' in a rccess,p, thereby lock- 23 ing the eam-platc E, which prevents its relation. Theshaftj may pass through thespring q, as shown. The free end of the spring 9 projects over the end of the pin-barrel D, and is adapted to be engaged by a prong or, projec- This prong s is arranged adjacent to the recess 0 in the end of the pin-barrel. As the prong 3 passes under the spring q, it lifts the same, thereby raising the pin 7' out of the recess 1), thus re- ;0 leasing the cam E. At this moment the recess 0 in the pin-barrel has encountered a point, in, on the cam, thereby turning said cam and shifting the barrel. As the barrel I) continues to rotate, the prong .9 passes away from under the spring g, which immediately 5 oted near its center to the under side of a plate, II, that is carried by the block Z,- but said lever G could be otherwise carried, if desired. The plate II is adapted to cover the wheel '1, lever q, and cam E. The lever or bolt G is operated by means of a headed pin, to, which passes throngh'a slot, 0:, in the platelI and into the said lever. By moving the pin to, and thereby the lever G, toward the pin or shaftj the projection a will enter a recess, a, and lock the wheel 13, and thereby also the shaftj and cam E. The pin-barrel may now revolve as many times as desired without changing the tune, it having no effect on the cam E. \Vhcn another tune is desired,

it is only necessary to disengage the lover or bolt G from the wheel '6 by disengaging the projection o from the wheel The lever G- is by preference springy and carries at its outer end a pin, y, adapted to enter recesses in the block Z to prevent accidental displacement of the said lever.

My tuneindicator consists of a spurwhecl,

I, hung in the support Z and in gear with the spur-wheel t. of numerals or other symbols to indicate which tune is being played. plate II registers with one of the symbols. Each time the cam E is turned to shift the pinbarrel 1) the wheel I, by means of the shaftj and spurwheel t,,will also be turned, thereby bringing the symbol representing the desired tune under the opening a".

Instead of the spur-wheel t having recesses a, the projection c on the lever G could enter between the teeth on the wheel to lock it. It is evident that the lever G- could operate directly upon the cam E instead'of upon the wheel I. It preferred, the index could be produced directly upon the cam E or wheel '15.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is-
